This could be a case of surgical site infection. Usually, this happens after surgery where there is an incision made thereby causing redness as well as swelling around where you were cut.

Make sure to visit your doctor so they can figure out what else needs to be done about this.

Based on that, it will be decided whether you eligible for liposuction or need some other procedure to remove fat from your face and double chin.
